Cold-seal packaging

Cold-seal flexible packaging is ideal for protein bars, breakfast bars, chocolate bars, nutritional bars, natural foods, ice cream novelties, and other heat-sensitive items.


We manufacture cold-seal flexible packaging by applying a water-based coating that adheres to itself and requires no heat to initiate a seal.

The advantages of cold-seal packaging

The seal strength and integrity are equivalent to that of heat-seal structures. But because cold-seal packaging requires no heat during the form/fill/seal process, cold-seal technology provides several advantages, including:

  • Cold-seal packaging line speeds can be multiple times faster than heat-seal line speeds.
  • It allows for immediate packaging line startup (as opposed to waiting for the packaging line to heat up).
  • Product spoilage due to packaging burn through is eliminated.
  • If the packaging line stops, heat-sensitive products will not get damaged due to the heat-sealing equipment.
  • Package distortion due to heat will be eliminated.
  • Energy costs are reduced. When using cold-seal packaging you no longer need to waste energy maintaining high temperatures on your heat-sealing equipment.
  • Operator injuries due to burns are eliminated.

Cold-seal flexible packaging can run on existing heat seal lines with heat turned off, which means lower energy costs. And faster line speeds = more throughput = more profit.

And your consumers will appreciate the superior product release of cold-seal packaging.

Common applications for cold-seal technology

Also known as “bar wraps”, cold-seal packaging is designed to be run on horizontal form/fill/seal equipment.

Common applications for cold-seal packaging include:

  • High-end snacking
  • Confectionery
  • Bakery
  • Health & fitness
